Strange lens on a Canon 5D ..

Thanks for the link. It's amazing how well that old lens performs. It looks better unsharpened. It seems to have almost as much resolution as modern equivalents but there's more spherical aberration and less contrast so it has a slightly softer look, which is really nice.

might be that his PP was at least partially responsible for the contrast,
but the resolution indeed has a very different feel - It was the very
first time I'd ever heard about the Coke Triplet

I think the Nikon AIS lenses are great, I just don't like the lack of autofocus, etc. When I shoot digital I want it to be easy.

editing had screwed the name - it was Nikkor 28/2 AIS, a very special
lens as its focusing cam seems to behave logarithmically: lots of leeway
close to MFD and then very little; excellent lens for hip shooting on
streets:
